This is the 140A Electromaax alternator. It is well built and hand wound. The front case is cast by Electromaax in Canada and has a universal adjusting ear for fitting it to many different engines. The bearings are over sized, it has dual internal fans, a built in regulator and the capability to be wired for external regulation as well, it also has heavy gauge hand wound windings that are 14GA. Beefy to say the least. The cases of these alternators are not painted and E-Maax claims it is to help them dissipate heat better.


I threw this one on the test bench at my local alternator shop before installing it and cold it exceeded 150A before the test machines belt could not handle it.
